Hello, I need a temperature controller for the recalculation pump for a hot water distribution system that works in a 4 stories villa with 900 (3x300) liter/day thermosyphon heat pipes solar water heaters that are hydraulically connected in a balanced way as a central system on the roof top of the villa. We need the temperature controller for the re-circulation pump that keep the water moderately hot in the distribution system to the final point of hot water consumption. Please advise on proper reliable product. I do not need the differential temperature controller as it is not designed for such a function. I understand that it is used for forced circulation solar water heating systems. Thanks for your anticipated reply.
